1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | |

2. |
Construct the inscribed square of circle 1, pointing up. | |

3. |
Draw the 45°, 135°, 225°, and 315° rays (with respect to the righthand half of the horizontal centerline) of circle 1, as shown. | |

4. |
Construct the inscribed square of square 2, with the angular points on rays 3. | |

5. |
Construct the inscribed square of square 4, pointing up. | |

6. |
Construct the inscribed square of square 5, with the angular points on rays 3. | |

7. |
Construct the inscribed square of square 6, pointing up. | |

8. |
Construct the inscribed circle of square 7. | |

9. |
Copy circle 8 four times, to the angular points of square 2. | |

10. |
Construct a circle centered at the righthand angular point of square 5, tangent to circle 8 at the righthand side. | |

11. |
Copy circle 10 four times, to the centers of circles 9. | |

12. |
Copy circle 10 to the intersection of circle 1 and the upper righthand ray 3. | |

13. |
Construct a circle centered at the lefthand intersection of the righthand circle 9 and the horizontal centerline, tangent to circle 12 at the lower side. | |

14. |
Copy circle 13 three times, to the corresponding intersections of the other circles 9 and the horizontal and vertical centerlines. | |

15. |
Construct a circle concentric to circle 1, tangent to circle 12 at the lower lefthand side. | |

16. |
Construct a circle centered at the righthand intersection of circle 13 and the horizontal centerline, tangent to the righthand circle 11 at the righthand side. | |

17. |
Copy circle 16 four times, to the intersections of circle 15 and rays 3. | |

18. |
Construct the "two-points" circle (defined by the two end-points of a centerline) between the center of the upper righthand circle 17 and the upper righthand angular point of square 4. See detail. | |

19. |
Copy circle 18 four times, to the angular points of square 4. See detail. | |

20. |
Construct two pairs of parallel lines, parallel to rays 3, tangent to circles 19 at both sides. See detail. | |

21. |
Copy circle 18 four times, to the intersections of circle 1 and the horizontal and vertical centerlines. | |

22. |
Construct two pairs of parallel lines, parallel to the horizontal and vertical centerlines, tangent to circles 21 at both sides. See detail. | |

23. |
Circles 8, 9, 11, 13, 14, and 17, and lines 20, and 22, are used for the final reconstruction. | |

24. |
Remove all parts not visible within the formation itself. | |

25. |
Colour all areas corresponding to standing... | |

26. |
...or to flattened crop, and finish the reconstruction of the 2018 Buckland Down formation. | |

27. |
The final result, matched with the aerial image. |
